The Red Devils trail 2-0 from the first leg at Anfield and, considering their stuttering form in front of goal, they'll need a huge performance to progress at their old rivals' expense. One early goal for Jurgen Klopp's men, and the tie could be finished for United.

Still, don't worry. Van Gaal has got a masterplan.

Okay, so we don't actually have any special insight into Van Gaal's tactics for the big match. However, we've tried our hardest to predict his approach to tonight's game.
